Re: Filter out TV-Logos ?

Hallo > Has anybody tried to filter out the annoying TV-Logos (zdf, pro7 in > Germany or maybe CNBC or the like) ? Is there an easy way or do I have > to work this out myself ? If you set a active size, and you have a 16:9 or 2.21:1 it will very likely disappear. Filtering or setting a certain area of the image to a color is currently not possible. If you only want to set a area to a certain color this should be no big problem. Take a look at the code of yuvscaler and yuvdenoise, that programm have the active size option. And can give you hints how it could work. auf hoffentlich bald, Berni the Chaos of Woodquarter Email: shadowlord@xxxxxxxxx bernhard.praschinger@xxxxxxxxxxxx www: http://www.lysator.liu.se/~gz/bernhard ------------------------------------------------------- This SF.net email is sponsored by: The Definitive IT and Networking Event.

[Solved]: driver-zoran-0.9.3 - DC10+ & SB pci128 OOPS

I found the problem, the card was just making crackle and pops when I tried to record with another (home made) program, so I moved the card to a different PCI slot. That solved the problem. - Ríkharður On Tue, Mar 25, 2003 at 10:26:31AM +0100, Ríkharður Egilsson wrote: > What a card, the DC10+ I'm realy impressed with the image quality, > By the way, what is the difference between the DC10 and the DC10+ ? > > My hardware: > Motherboard: Abit BP6 (Dual Celeron 366MHz@366MHz) > DC10+ video capture card. > Sound Blaster pci128 > All the Hard disks are connected to the HighPoint > UDMA controller. > > Recording video only (i.e. no sound) works without any problem. > I can also use lavplay to play the recording back to the TV in > broadcast quality.

yuvfps and sound

Hi Got a fabulous NTSC video from USA and would like to make it a PAL DV file. Acquisition is Ok, no worries, thanks to Canopus. Although I am not sure if I have to use AVI1 or 2 to use it with lav2yuv. The frame rate : should I use yuvfps 25000:1000 or 25:1 (it has to go back onto video) I guess the sound will have to be resampled, I know we people came around this question already but can not find it in my archives. Thanks a lot for your help Edouard ------------------------------------------------------- This SF.net email is sponsored by:Crypto Challenge is now open!

Although I am not sure if I > have to use AVI1 or 2 to use it with lav2yuv. Ah, another Canopus convert ;) Why not use raw DV? I use 'dvgrab' with "--format raw" and then use 'smil2yuv' to get the yuv4mpeg2 and audio. Something like this: 'smil2yuv -a audio.wav raw.dv | ... | mpeg2enc ...' > The frame rate : should I use yuvfps 25000:1000 or 25:1 (it has to go back > onto video) No need to worry about that because smil2yuv generates the correct rate information in the yuv4mpeg2 header automatically. > I guess the sound will have to be resampled, I know we people came around > this question already but can not find it in my archives. mp2enc will downsample the audio from 48 to 44.1K but that may not be necessary. If you're making a DVD then 48K audio is the correct format. If you're making a SVCD then 48 might still work - my players all accept the higher rate even for VCD/SVCD discs.
